New study explores Fine-Tuning ventilators to improve oxygen flow in ARDS

NCT ID NCT06919484

Knowledge-focused Sponsor: Southeast University, China Source: ClinicalTrials.gov ↗

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how changing the way a ventilator lets patients breathe out (called RCexp) affects air and blood flow in the lungs of people with ARDS. Researchers will use a special imaging technique (EIT) to measure these changes in 60 adults on ventilators. The goal is to understand if adjusting the breathing machine can improve lung function.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
RCexp (expiratory time constant adjustment during mechanical ventilation)
What this could lead to
If successful, this could help doctors better set ventilators for ARDS patients, potentially improving oxygen delivery and reducing lung damage.
What could go wrong
This is a small, early physiological study with only 60 participants, focused on measurements rather than clinical outcomes. It may not lead to direct treatment changes.
